ABSTRACT

Resumen El espasmo hemifacial se caracteriza por contracciones tonicoclónicas en los músculos inervados por el nervio facial, causado por la compresión del nervio facial por una arteria, generalmente la arteria cerebelosa anteroinferior o venas del ángulo pontocerebeloso. Suelen aparecer espontáneamente, debido a la tensión emocional, fatiga, y disminuyen durante el reposo. Se presenta entre los 13 a 77 años con una duración de los síntomas aproximadamente de ocho años. La inyección local de toxina botulínica puede ser efectiva en el tratamiento, y la descompresión microvascular está reservada para casos refractarios al tratamiento médico, con resolución completa entre el 85 al 93%. En este artículo, se resumen las principales características anatomo-clínicas, fisiopatológicas, y una descripción detallada de la descompresión microvascular como mejor opción terapéutica.


Abstract Hemifacial spasm is characterized by tonic-clonic contractions of the muscles innervated by the facial nerve. It is caused by compression of the facial nerve by a blood vessel, which usually is the anterior inferior cerebellar artery or the veins of the cerebello-pontine angle. It typically appears spontaneously, caused by emotional tension and fatigue, and it's reduced during rest. Likewise, it presents between the ages of 13 and 77 years, with a median duration of symptoms of eight years. Treatment with local botulinum toxin injection can be effective, and the Microvascular decompression is reserved for cases that are refractory to medical treatment, resulting in full spasm resolution in 85 to 93% of patients. This article summarizes the main anatomic-clinical and physio-pathological characteristics of hemifacial spasms. Additionally, a detailed description of microvascular decompression as the best therapeutic option is described in detail.
